80mm Dual-Bearing Wheel with TPU Tire

I wanted to provide an option for printing wheels for this model Plywood Dolly by JohnMartin | Download free STL model | Printables.com since roller blade wheels can be expensive.

Hardware (per wheel)

1. 5x M3x10 Screws
2. 5x M3 nuts
3. 2x 608 bearings 

I used ASA for the center parts with 3 walls and 50% gyroid infill.  The TPU tire was printed with 10 walls to make sure it was solid. If you want it softer, adjust accordingly.
